Personally, I love idoser on iTunes/Spotify I find them very relaxing and I love light sensation feeling a bit high, minus any drugs or alcohol, beginning to appreciate how soothing it is and also found that I can just the beats suit the activity I am working on, for example, intense focus, I got to get project done or that blog post, assignment study for a test.
However I do love the ones on youtube, they can be soothing for bed or relaxation.. I can get whatever that needs to be done, without overthinking everything or thinking about unrelated topics. I have even found that iI have started to keep a notebook with me to jot down tasks to do and anything else that's random.
Anyway, I have just registered to do a few online courses just to keep myself occupied over the next few months before the August/September which should be good. I want to feel productive but often struggle because of the pain/fatige and brain fog.
